Over here in NSW there is a fixed fee set by Fair Trading ($28, I think) for strata managers to give access to owners to view records. They are also permitted to charge more for photocopying etc.
As far as what you consider to be their duties, you have a point. But if your strata manager was one of those guys who in NSW makes the bulk of their profit on Schedule B charges, it could be a much more expensive proposition.
Getting back to your situation, if it isn’t in the contract or part of strata laws (and I have no idea if it is) then it isn’t a duty.
